白兰花挥发性成分的GC-MS分析
Chemical Constituents of the Volatiles of Michelia alba DC by GC-MS
摘要
Abstract
Ethyl acetate was used to extract the volatile compounds with ultrasound assistance of Michelia alba DC which was dried in the shade or stored in -40 t, and supercritical fluid extraction (SFE) with CO2 was used to prepare the volatile oil. GC-MS detected 59 volatile compounds in the four samples, and these determined compounds occupied 98.87%, 99.72%, 92.77% and 96.21% of the total peak area, respectively. The main constituents of the volatile compounds were Linalool (7.50%, 17.61%, 67.51% and 70.42%), Phenylethyl alcohol (0.84%, 1.36%, 2.57% and 2.61%), propionic ether (38.21%, 6.36%), and toluene (34.52%, 66.88%). Moreover, linalool, the characteristic fragrant composition of Michelia alba DC was high in the extract of Tincture and volatile oil from SFE. This study could provide scientific basis for the profound exploration and utilization of Michelia alba DC.关键词
